T0 at whom it may concern.-

Be it known that I, GEORGE IV. MILES, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCut-Offs for Paper-Box Machines and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

The object of the invention is to construct a paper-box machine with acut-off which shall be automatic in its operation and which may also beoperated by devices independent of the principal cut-off mechanism.

In the accompanying drawings, Figure 1 represents a perspective View ofa paper-box machine having my improvements as in use when applying apaper strip to the sides and ends of a box. Fig. 2 is a side view of themachine as it appears when used for cutting the paper strip applied tothe top of a box. Fig. 3 is a sectional view illustrating theworm-gearing through which the shaft which carries the box-form isdriven and other details. Fig. 4 represents two parts of a cam and aslotted plate which are employed in connection with the shaft whichcarries the box-form. Fig. 5 is a plan view illustrating an adjustableplatform. Fig. 6 shows a crosssection of a hollow bar or housing inwhich a worm-shaft is mounted. Fig. 7 is an end view showing the end ofthe machine on which the cutters are mounted, with a platform inposition for applying the paper to the top of the box. Fig. 8 shows asection of a cam on a shaft on which a box-form is mounted. Fig. 9illustrates a swivel connection of a rod with an arm of thecutter-shaft.

A designates the supporting-frame, which is provided with two parallelrods or bars B, to which are suspended the hanger-bearings C for thejournals cl of a ribbon-spool D. E indicates the ribbon or strip ofpaper which passes from said spool through the guides F over the roll G,which rotates in a paste-box G", then over a guide-roll H and over astationary cutter R to the box on which the paper is to be pasted. Thesaid box is placed on a box-form I, which is removably mounted on arotative shaft J, which has bearings 7s on-a horizontal hollow bar orhousing K, secured to the supporting-frame by bolts L, passed through aslot Z in an arm or lug it. (See Figs. 6 and 7.) The guide-roll H hastwo heads connected by transverse wires, so that as little of thepaste-surface of the paper ribbon as possible shall come in contact withsaid roll, the latter being mounted in bearings carried by the frame A.The operator manipulates the paper ribbon so as to paste it on the boxas the shaft J revolves.

Mounted at one end of the frame A is a cutter-frame, which has two sideparts 1, which are adj ustably connected with'two inclined rods 2, whichare made fast at their lower ends to a cross-bar of the frame A, and thecutterframe may be adjusted upward or downward on said rods 2 by meansof the set-screws 3, to adapt it for boxes of different sizes.

To a cross-bar of the cutter-frame is adj ustably secured a stationarycutter-blade R, and in the upper part of said frame is mounted acutter-shaft Q, from which extend the curved arms g, which areadjustablysecured to the shaft Q by set-screws. To the free ends of thearms q is secured a cutter-blade R, which is inwardly inclined tocorrespond with the bevel of the cutting-edge of the stationary blade R,and also to make a shearing cut.

011 one end of the shaft J is secured a cam, which is made in two parts,the central part being formed of a circular disk J, which has a rabbetedor flanged edge and is fast on said shaft J. The other part of said camis formed of a ring-disk M, into which the disk J is fitted, as shown inFig. 8. A thumb-screw M, in a threaded hole in the disk J, is used totighten the ring-disk M thereto, and a screw M passed through the disk Jso that the head of the screw will bind the ring-disk, serves to holdthe two parts of the cam together when the thumb-screw is turned toloosen the ring-disk to adjust it in position on the circular disk.

The ring-disk M is formed with a notch or cavity m and a cam-form m, andthe ringdisk is adjusted on the circular disk with the N indicates aslotted plate having at oneend a stud n, on which is placed africtionroller n At the opposite end of said plate is a socket 01through which is passed one end of a rod 0, which is connected with acylindrical bearing 1f, which moves in the slot a of the plate, and aspring n is placed on the rod 0, between the socket n and thecylindrical bearing. The upper end of the rod 0 is held in a sleeve P,which is adjustable on the rod and is swiveled to or loosely connectedwith a crank-arm q of the cutter-shaft Q. The plate N is movableconnected with the shaft J, the latter extending through a slot 72 insaid plate to allow a longitudinal movement of the rod 0, and the cam MJ is secured to the outer extremity of said shaft after the shaft hasbeen passed through said plate.

Rotary motion is imparted to the shaft J, which carries the box-form andthe cam M J, through a worm-shaft O, which is in gear with shaft J andis mounted in the hollow bar K, as shown in Fig. 3, a wheel on shafts Oand belting being indicated by 0 At the box-form, with the box thereon,is rotated, the cam, moving against the roller 71 on plate N, draws therod 0, which is connected with an arm on the shaft of the cutter R, andthe cutter is thus raised the required height, and when the roller slipsfrom the cam, as the cavity m is reached, the cutter R descendsautomatically by gravity and severs the paper ribbon.

S indicates a platform which is used to hold the box in position forpasting paper on the top. (See Figs. 2 and 5.) The said platform issupported by a bracket U, which is adj ustably secured to a verticalshaft V, mounted in bearings carried by the frame A. The said platformis secured to the bracket by means of a thumb-screw T, passed throughahole in the bracket and through a lug on the lower side of theplatform. to the shaft V by means of a screw t and a clamp 15. \Vindicates a right-angular plate having a slot 10, said plate beingadjustably secured in position on the platform to hold the box, placedthereon, in the right relative position for applying the paper strip.The plate V is secured by a thumb-screw w, which is passed through acleat s of the platform and a slot w of said plate. A set-screw t iscarried by an arm a of the bracket, said screw forming an adjustablestop for contact with the main frame when the platform is swung to thefront of the machine for use. hen not in use, it is in a depressedposition at one side of the machine.

lVhen the paper is to be pasted to the top of the box, the box-form withthe box thereon is removed from the shaft J, the clamp 25 on the shaftVis loosened, and the platform is raised, the clamp is again tightenedand the platform is swung around to its proper p0- The bracket issecured sition in front of the machine. The box-form with the box isthen placed on the platform, its position being regulated by the plate Wand cleat s and the paper is applied to the top of the box by theoperator. Cut-off mechanism, independent of the shaft J and its drivingmechanism, is provided and is employed for cutting the paper whenapplied to the top of the box. A foot-treadle X is pivoted to a plate m,secured to the floor or to the base of the machine, and a cord Y isconnected with the treadle, passed over a pulley 3 mounted on the bar K,and connected at with the rod 0. I

The cutter B being held in its raised position by the spring n on therod 0, the operator presses the treadle X with his foot when the paperis to be cut, thus moving the said rod upward and partly rotating thecuttershaft, so that the cutter-R descends and severs the paper strip.

The cutter-frame being adjustable on the fixed oblique rods 2, and thecam with the adjustable ring-disk, formed wit-h the cavity m, areconsidered important features of the machine.
